Recently I have installed wine to use barahdirect software which is a roman to devanagari unicode software which works wonder in windows. but after installing wine, I see that each time I boot my system and switch on my broadband modem, I am automatically connected to internet although I had to run following script to connect to internet previouslly
sudo ifconfig eth0 192.168.1.2 netmask 255.255.255.0 up
sudo route add default gw 192.168.1.1 eth0
sudo pppoeconf
sudo pon dsl-provider
sudo /etc/init.d/networking restart
plog

A googling has frightened me about installing wine with root privileges. I am unable to know whether the wine has root priveleges or not. THis is the MOST FRIGHTENING THING for me at this moment.
Also, rhythmbox goes out after a selection of file is made to open.
Is this related to wine anyway?
